Wheel.



WY T [VESSE S J. L. LA DRIERE. WHEEL. APPLICATION FILED APR. 1, 1912.

, adjacent the side walls of'the sections 14 and 16, respectively. By virtue of the hub being provided with the ribs 12 and the teeth 13, and the outer portion of the'casing being provided with the ribs 22, ,and the 'end portions 23 and 24 thereon, it will be manifest that the pneumatic tube 11 will be strongly keyed th the hub and the outer casing portion so as to prevent creeping of the tube around the hub or'creepingof the outer casing portion'arouhd the tube. It will also be manifest that such construction assures the transmission of rotary motion from the hub to the outer portion of the wheel, or from such outer portion of the wheel to the hub, and this without the imposition of undue strain on the pneumatic tube", and with out detracting from the resiliency or cushioning capacity of the inflated tube. This latter is due to the fact that the pressure against the tube will be in spots. In other words, the pneumatic or inflated tube will be held between projections on the hub and outer casing portion, and will be allowed to be resilient as ifthe stress was only at one spot or place-at one time, as contradis tinguished from a tube that is disposed in.

an annular chamber the wall or walls of which are plain-and free of projections such as ribs 0:. teeth.

Incidental to the use of my novel wheel,

it will be manifest that the hub is enabled to move freely in a vertical direction in the outer casing portion, and is efficiently cush ioned in said outer casing portion, with the result that the transmission of shock and jar from the outer portion of the wheel to the hub and the vehicle to which the hub is connected,-is effectually prevented. 7

While I prefer to employ the specific numbers of ribs and teeth as stated, it is obvious that the said numbers may be varied without involving departure from the scope of my claimed invention;

In addition to the advantages ascribed to my novel wheel, it will be noted that the same is simple and inexpensive in ccinstruction, and by reason of such construction is well adapted to withstand the usage to which wheels of corresponding character are ordinarily subjected.

Having described my invention, what I romeo? I claim-and desire to secure by Letters-Pat- W cut, is: v 1

, 1. In a wheel, the combination of a hub having a circumferential groove and trans? verse ribs in the bottom of said groove, and a larger number of teeth at the sides of the groove, an annular cushion disposed in the said groove of the hub and surrounding the;

hub, and an outer casing portion surround ing the hub and the annular cushion in a manner to permit of vertical movement of the hub within said casing portion and having transverse ribs arranged in radial alinement with the-spaces between the teeth of the hub and also having inwardly extending end portions on the said ribst,for the purpose set forth. i

'2. In a wheel, the combination of a hub comprising an inner section having an an-,

nular groove in its inner side and an outer" sectionhaving a central recessin its outer side, said hub having a circumferential groove and transverse ribs in the bottom of the groove and a greater. number of teeth on the sides of the groove, transverse bolts connecting the said sections and having their heads disposed in said annular groove, nuts mounted on the outer ends of said bolts and disposed in said [central recess; an inflated tube surrounding the hub and seated in the circumferential groove thereof and having an inflation tube the outer end of which is disposed in said central recess;'and an outer casing portion surrounding the hub and the inflated tube in a manmy hand in presence of two subscribing witnesses.
